He never bought the official Ultimate upgrade. But he did buy the Warriors Orochi 4 Ultimate soundtrack on iTunes, and a Hades figure from AmiAmi. In his mind, he’d paid his dues.
Prologue: The Cartridge That Wasn’t Enough It began like any other Tuesday for Kaito, a veteran musou fan with a shelf full of Dynasty and Samurai Warriors games. He had bought Warriors Orochi 4 at launch on Switch—cartridge in hand, plastic still smelling of factory newness. He loved the chaotic deity-smashing, the ridiculous pairings (Zeus and Lu Bu? Yes.), and the portable chaos. Warriors Orochi 4 Ultimate Switch NSP UPDATE DLC
He also discovered that the upgrade wasn’t just a flag. The game checked for a specific title ID ( 0100E2900B6A6000 for US, 0100E2B00D48A000 for JP/EU). Installing the wrong region’s update would break DLC compatibility. He triple-checked: US base, US update, US DLC. Epilogue: A Stable Slice of Chaos Six months later, Kaito had logged 200 hours. He cleared Infinity Mode’s 100 floors with Hades, maxed out every character’s proficiency, and even used Edizon to unlock the “Play 1,000 battles” achievement because life is short. His Switch’s emuMMC was a time capsule of Warriors Orochi 4 Ultimate —the definitive, complete, offline-forever version. He never bought the official Ultimate upgrade
Kaito typed slowly: “Look for the Gaia’s Sandals repack. v1.0.16 merged. Install with Awoo. Don’t forget sigpatches. And if you enjoy it, buy a t-shirt or something.” Prologue: The Cartridge That Wasn’t Enough It began
The title screen now read with a new menu option: Infinity Mode. He checked the Gallery—all DLC characters unlocked: Gaia, Hades, Yang Jian, Ryu Hayabusa (from Ninja Gaiden), Joan of Arc (from Bladestorm), and even the pre-order “Sacred Treasure Costumes.” Every weapon pack, every BGM track from previous Orochi games. 170+ characters. Complete. Chapter 4: The Update Labyrinth But v1.0.13 wasn’t the final version. Over the next few weeks, Kaito noticed bugs: infinite loading in Infinity Mode’s floor 30, a softlock when using Gaia’s magic too quickly, and missing voice lines for the Warriors All-Stars collab characters. The official eShop had v1.0.14, then v1.0.15, then v1.0.16.
Solution: He used Tinfoil (the homebrew app, not the foil) with the “install unsigned code” option enabled. Then he ran Lockpick_RCM to dump his own Switch’s keys, converted the DLC NSP to a “proper” install using NSC_Builder , and reinstalled. The costumes unlocked. Some purists on the forums argued that converting the whole thing into an XCI (cartridge image) was cleaner. Kaito tried it using SAK (Switch Army Knife). He merged the base + update + DLC into a single 17.3GB XCI, but loading times increased slightly—the Switch’s SD card reader struggled with the large file. He reverted to separate NSPs installed to NAND (internal storage) for faster access.
His heart sank. He checked forums: common issue. The solution? Boot into maintenance mode (hold volume up/down on launch), clear the cache, then reboot. He did. The second launch worked.
